Role of Acidophilic Methanotrophs in Long Term Natural Attenuation of cVOCs in Low pH Aquifers

Abstract

The main focus of this Limited Scope SERDP project was to determine the extent to which methanotrophs may contribute to the biodegradation of chlorinated volatile organic compounds (cVOCs) in low pH groundwater aquifers. Our objectives included (1) determining whether methanotrophs exist in acidic groundwater aquifers and are capable of degrading methane and cVOCs, with a specific focus on trichloroethene (TCE); and (2) to identity of the key methanotrophs and/or methane-oxidizing genes present in acidic groundwater systems using advanced molecular techniques, including stable isotopeprobing (SIP). The role of methanotrophs in biodegrading cVOCs in low pH groundwater has received little study as has the potential to enhance their activity with methane or other amendments.
